DROPPER FOR DISINFECTING APPARATUS- Patented Jan. 2, 1906.

Application filed May 18, 1905- Serial No. 261,052.

To all whom it may concern:

Be it known that LVVILLIAM H. ROSE, acitizen of the United States, and aresident of Baltimore,Maryland,have invented certain new and usefulImprovements in Droppers for Disinfecting Apparatus, of which thefollowing is a specification.

This invention relates to improvements in disinfecting devices of thatclass in which a disinfecting fluid is gradually discharged from a tankor container and permitted to drop into or upon the article to bedisinfected.

The object of the present invention is to subdivide the discharge fromsuch a disinfecting apparatusinto small drops, so that with agiven flowof fluid the interval of time between the drops shall be shorter and theapplication of the disinfectant more nearly continuous than heretoforewith apparatus of this kind.

The invention will be described in connection with the accompanyingdrawings, in which- Figure 1 is a central sectional view of adisinfecting apparatus. Fig. 2.is a side view of the dropping device.Fig. 3 is a sectional view of the dropping device upon the line 3 3 ofFig. 2; and Fig. 4. is a view similar to Fig. 3, showing a slightmodification.

My present invention can be used in connection with ,any disinfectingapparatus of the type in which the fluid is discharged in drops.

In Fig. 1 of the drawings I have illustrated one form of disinfectingapparatus which was patented to me January 16, 1900, in Letters PatentNo. 641,548. For a detail description of this apparatus reference ismade to said patent. The apparatus illustrated comprises a fluid tank orreceptacle 10, in which there is a float 11, carrying a wick 12, whichis U- shaped and adapted to siphon the fluid from the tank and dischargeit into a receptacle 13 beneath the tank. The receptacle 13 isperforated to permit a portion of the disinfecting fluid to evaporate,and it is provided with an absorbent pad 14, which holds a considerableamount of the fluid and presents a broad surface for evaporation. Theexcess of fluid is dischargeddrop by drop from a pipe or opening 15 inthe bottom of the compartment 13.

My present invention relates to a dropping device which may, forinstance, be attached to the discharge-tube 15 of the apparatus shown inFig. 1. This device A preferably consists of a tube 16, having aconsiderable opening therein, which is not liable to be choked bysediment, and terminating in a depending point 17 upon which the fluidgathers and from which it is dropped. As shown in Figs. 1, 2, and 3, thepoint 17is formed by cutting the tube upon a diagonal plane at an acuteangle to its axis, as indicated at 18. The extreme point 17 may betrimmed or shaped until it is sharper than would result from shearing onthe plane 18.

I preferably surround the dropping-point 17 by a casing 19, connected tothe tube at its upper end and having an open mouth somewhat below thepoint. The function of this casing is to protect the point from injuryand also to facilitate its operation by preventing air-currents fromevaporating the fluid or causing it to flow irregularly.

In Fig. 4 I have shown a slight modification in which the point 17 isbrought into line with the axis of the dropping-tube 16". This permitsof the use of a narrower and more graceful casing 19, having acorrespondingly small opening 20 in its lower end. The tip or point 17is preferably arranged centrally above the mouthQO. This constructionprevents sticks or other obstructions from being passed up into thedropping-tube 16. As shown in this figure, the point 17 is a separatepiece connected to the tube 16*. A strong and sharp point, such as aneedle-point, may thus be used for the purpose of finely subdividing thefluid without unduly weakening the construction. By means of the sharpor attenuated point with which the droppingtube is provided the fluid isdischarged in comparatively frequent and relatively small drops, whereasin apparatus constructed as shown, for instance, in my prior patent thefluid is discharged in large drops and at relatively long intervals.

It will be evident that my invention may be embodied in various formsand applied to various kinds of disinfecting apparatus.

Without limiting myself to the precise construction and arrangementillustrated and described, I claim 1. The combination, in adisinfectingapparatus, with afluid-tank and means for maintaining a slow dischargeof fluid therefrom, of a dropping device comprising an open discharge-tube and a relatively slender solid point depending therefrom and fromwhich the fluid drops.

2.
